This ringe or drapery is of such maire as to pend vert1cally and present a neat appearance and at all adgustments of the back cover as not to expose any o:t' the opening and thereby hide the operating mechanism associated With the back.

The arms C are snitably upholstered and are hingedly connectedat tl1eir rear ends to the frame of the back B in any preferred 'Way, as indicated at 11, and are adjnstably supported at. theirzfront ends from the frame of the seat. comprises. members 13 and 14 which are telescopically related, the mem bcr 13 .being secured at its lower and to the corbel6 of the rail 1 and inclining upwardl andforwardly to receive the member 14 which is attached to the ar1n C and depends therefrom at a rearward.and clowhward inclinatien to correspond With the upward and forward inclination of the member 13. A curved slot-15 is formed in the member 14 and receives a pin 16 carried by the uppcr end of the member 13. Theparts are relatively disposed to insnre 1nocment of the arms C With the back B, the member 14 sliding freely in the member 13 and at all stages of adjustment forming asupport for the outerends of the :1rms. VVhen the back B is elevated, the arms C correspondingly rise, and When the back is.lowered, the arme aresimilarly lowered. The connections, are

so arranged that the arms C always re'main parallel to a given position When adjusted. The adjustmentof the arme 0 is automatic z}pnd is concurrent with the adjustment ofthe ack.

A transverse shaft 17 is secured at its ends to fittings 18 attached to the inner side of the rails 1. Admm19 is loose upon the shaft 17 but prevented .from moving longitndinally thereon. A toothed wheel 20iS provided at each side of the d'rum 19 and is loosely mounted upon the shaft 17 but, like the drm 19 prevented from moving longitudinilly thereon. Each of the toothed Wheels20 is provided upon its outer side with a polygonal portion 21 to receive a wrench or other appliance to admit of rotat ing the toothdwheel when it is reqnired to adjust the tension et a coilspring 22 and toothed whecl 20, respectively.

The adjustable. support to the adjacent rail 1.

mountd npon the shaft 17 and having con nection 'at opposite encls w1th the drmn 19 spring actuated latch'23 is in cooperative relation With each of the toothed wheels 20 to hold the same in the required adjusted position and thercbydnaintain the tension of the spring 22. The spring aetuated latChes 23 are m0unted in fittings24carried by a crosspiece 25. The drum'19 is providedwith a toothed portion 26 with whiclr a latch 27 cooperates to hold the drain in a given position. The latch 27 is 1nounted in a fitting 28 similar to the fittings 24, the fittii1gfl 28 being carried by the crosSpiece 25. A -shaft 29, mouhted in the longitudinal rails 1 of the seat trame has its ends projecting and provided with knobs 30 whereby the shaft maybe turned When required. An

arm 3l,'projectingfrom the shaft 29, is

linked to the latch 27 so that rotation ot the shait 29 in one direction withdraws the latch 27 frorn engagementwith the toothed portion 26 of the drum 19 Which may then turn freely upon the shaft 17. A spring 32,

mounted upon the shaft 295 is connected at one end to said shaft and at its opposite end The spring 32 is normally under tension torotate th shaft 29 in one directionso as to hold the latch 27 in engagement with the toothed portion 26 and thereby hold the drum 19 from rotating in either direction. The arrangement is such that the shaft 29 ma bc operated from either side of the longue as may be fonnd most convenient. A cuived bar 33, pii7oted at its upper end to the back. dependstherefrom and engages a bracket 34 secured to the crosspiece 2 at the rea1 end of the seat trame. The bar 33 is formed with a slot 35 which receives a pin 36 snpported in the spaced 'clements' of the bracket between which the bar 33 passes. A cable 37, or likc part,is attachd at one end to the lower end of the bar 33 and at its opposite end to the ,drum 19 and is partly wound upon the v latter. nnder tension which is regulated by turning The coil -springs 22 are. normally the toothed wheels 20 and it is preferred to have the tension Suclras to efiect an elevation of the back B when the drum 19 is relcased. this being accomplished by tlie winding of the cable 37 upon the drum by' the action ol: the springs 22. VVhen it is required to adjnst the tension of the Springs22, the drum 19 is held stationary engagement of the l'atch 27 with the toothed portion 26 thereofand the latches 23 are inoved to clear the toothed whcels 20, which latter are'rOtated tlirogzh the instrumentality of a wreiich or other appliance fitted to the part 21. After the.

springs22 have been properly tensioned, the latchs'23 rare permitted' to engage the toothed Wlieels 20, 'thereby -maintainihg the tension imparted'to the springs. Upon operating the shaft 29 to disengage the latch 27 'from the toothed portion 26, the drum 19 is rotated by the action of the springs 22, thereby Winding the cable 37 thereon and elevating the bar 33 and the back B. When the back reaches the required elevation, tne

shaft 29 is released, thereby throwing the latch 27 into engagement With the toothed.

Wheel 26 and preventing urther rotation of the drun1 19 and holding the baok B and th ar1ns C in the required adjusted position.

VVhat is claimed is: 1. In adevice of the charaoter speoified, a scat a baok pivoted to the seat, arnns having pivotal connection with the back and movable therewith, and telescoping supports between the outer ends of the arms and the scat and rigidly connected thereto, respectively. and inclining upwardly and for toothed wheel, a spring connection between the toothed wheel and drum, the tension of said spring being adjustable loy rotation of the toothed wheel, and means independently of the first mentioned means for holding, the

toothed wlieel in the required adjnsted position.

4. In a device ofthe chara cter specified, a seat, an adjustable loack, a shaft, a drun1 loose on the shaft, toothed wheels loose on the shaft, spring conneoting means between the toothed wheels and drum, latches for holding the toothed wheels in required adji1sted position, a latch in cooperative relation With the drn1nfor holding the same in roqu'ired adiusted position, a manually operalole sliaft for releasing the latch coacting With the drum, and connecting ineans between said latoh and mannally operable: shaft.

5. In a device of the class described, an adjnstable back, a shaft below the back, a drnm loose on said shaft, a calole connected to said drum, means connecting said cable to the hack, a crosspieoe below the back on the side of the shaft opposite to said means,

the drum, a toothed wheel loose on the shaft a helical spring surrounding the shaft and connected at one end to the drum and at the other end to the toothed wheel, and a latch operable independently of. the first mentioned la'toh mounted on said cross pieceand alatch on said cross -piece coacting With coaoting with the toothed wheel to regulate the tension of said spring.

In tesmony whereof I afiix my signature 1n presence of two W1tnesses.
